Re: Kids bike

Auto parts/hardware store?? Maybe get a thread insert kit?? It's either that or replace the crank.

I'll leave this thread here.....maybe could be in DIY. I haven't found a bike support section so this looks like as good a place as any.

Re: Kids bike

What the pedal attaches to....not bad but no fun to replace. Could have the pedal welded if you don't plan on replacing the pedal at any time. (last resort)

Re: Kids bike

It maybe reversed threads. Older bikes used reverse threads on one side. Try screwing it in the other direction.

Re: Kids bike

Depending on the age and 'style' of bike, it could be a stripped thread on the pedal or the crank.

Pedals tend to be made of steel, whereas cranks are an aluminium-alloy for lightness but, it's quite a 'soft' metal - Lots of strength but it can't take any wear-and-tear'.

Also, the method of attachment to the 'axle-shaft' (the steel rod that goes through the frame and the cranks fixes on to) varies. Some are a straight-forward nut on a threaded axle, whilst others use a bolt that screws into the axle. Again, some nuts (or bolts) fit on clockwise, others fit counter-clockwise. A good test is that, as the pedal/axle is turned, the rotation should tighten the nut/bolt, rather than loosen it.

If you're moderately good as an engineer/mechanic, it's a fairly simple job to sort out - The sort of job that, it's harder to find a shop selling the exact bits, than it is to mend it :laugh:

Re: Kids bike

The only thing to remember, if removing the axle from the frame, is to catch the ball-bearings if they fall out - Some are mounted in a 'cage', others are loose.

If they're loose bearings, thoroughly smother their tracks with thick grease to hold the bearings, when putting 'em back in :grin:

The reason it screws in anti-clockwise is, when pedalling, it tightens the pedal to the crank - There's nowt more embarrassing than a pedal falling off every hundred yards or so :grin:
